Question

Use the net to find the surface area of the prism.

Answer 1

`286ft^2`

Explanation:

The rectangular prism has a total surface area given by

`T.S.A=2(lw+lh+wh)`

where
`l=5ft,w=9ft,h=7ft`

Substitute the values into the formula to get;

`T.S.A=2(5*9+5* 7+9* 7)`

Simplify

`T.S.A=2(143)`

`T.S.A=286ft^2`

Answer 2

The correct answer option is 286 feet^2.

Explanation:

We are given a rectangular prism with the length of 5 feet, width of 9 feet and a height of 7 feet.

We know that the formula of the surface area of a rectangular prism is given by:

Surface area of rectangular prism = 2 ( wl + hl + hw )

Substituting the given values in the formula to get:

Surface area of prism = 2 {(9 * 5) + (7 * 5) + (7 * 9)} = 286 feet^2
